How do you find the diameter of a circle that has an area of 201.1?

Hi there! Hopefully this helps!

We know pi*r^2 gives the area of the circle. And the diameter is 2*r.

Now the area of the circle is 201.1 in^2.

Therefore 201.1 = pi*r^2

=> r^2 = 201.1 / pi

=> r^2 = 64.0 (approximately)

=> r = sqrt 64

=> r = 8

Diameter = 2*r = 2*8 = 16

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
